To reveal cracking resistance of fiber reinforced concrete (FRC), an experimental investigation was conducted on concrete with various types of fibers (straight steel fiber, amorphous alloy straight fiber, and steel fiber+amorphous alloy fiber) and various volume fractions (1.0%, 1.5% and 2.0%) to evaluate early cracking behavior and post-hardened fracture toughness. First, the concrete early cracking feature was quantitatively analyzed by using plate method and image quantitative technique, aiming to evaluate early cracking behavior of FRC. Then, the three-point bending tests were conducted on notched prism specimens, the hardened fracture toughness of FRC was analyzed and assessed based on the double K fracture parameters. The results show that the single steel fiber reinforced concrete and hybrid fiber concrete exhibit the best cracking resistance at early age. As the fiber fraction increases from 1.0% to 2.0%, the unstable fracture toughness of steel fiber, amorphous alloy fiber, and hybrid fiber reinforced concrete increases by 58.9%, 44.3% and 55.5%, respectively. Meanwhile, the fracture energy of hybrid fiber concrete with 2.0% fiber reaches 11.8 times that of normal concrete. It shows that steel and amorphous alloy fibers have a synergistic effect at different periods of concrete hardening process. As a result, steel fiber and amorphous alloy fiber have a synergistic effect at the different periods of the hardening process, the hybrid steel and amorphous alloy fibers can not only prevent the early-age concrete plastic cracking but also effectively control the formulation and propagation of post-hardened tensile cracks, thus, achieving a staged anti-crack purpose. Considering the early cracking properties, post-hardening tensile properties, and fracture properties of concrete, the overall performance of hybrid fiber concrete with the same fiber content shows better performance.
